Problems solved by technology

[0002] At present, the copper nut sealing device of the stop valve used in the air-conditioning industry is a copper spherical gasket. It is very difficult to operate the copper spherical gasket during factory assembly, because the spherical gasket is placed in the copper nut alone, and it is easy to tilt and misalign during assembly. It leads to low production efficiency; at the same time, the inclination or misalignment of the spherical pad can easily cause defective products that are not assembled in place to flow into the market, and due to poor sealing, it is easy to cause dust, impurities, etc. to enter the system; dismantling, high cost

Abstract

The invention provides a sealing device, which is used for sealing a copper nut of a shut-off valve. The copper nut has a stepped hole passing through it. The sealing device includes: a guide post and a limit ring, the guide post is inserted into the stepped hole, and the stepped hole is sealed; The limit ring is arranged at one end of the guide column, and is stuck on the step of the step hole. In the sealing device provided by the present invention, the guide post has a guiding and positioning function on the basis of satisfying the sealing function, so that the sealing device is easier to assemble into the copper nut, thereby improving production efficiency and improving the assembly qualification rate; The ring is stuck on the step of the step hole to limit the position of the sealing device to avoid loosening and falling off of the sealing device, which further ensures the reliability of the sealing device; and the sealing device can be made of plastic or rubber material, which greatly reduces the cost.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a sealing device for a copper nut of a shut-off valve. Background technique [0002] At present, the copper nut sealing device of the stop valve used in the air-conditioning industry is a copper spherical gasket. It is very difficult to operate the copper spherical gasket during factory assembly, because the spherical gasket is placed in the copper nut alone, and it is easy to tilt and misalign during assembly. It leads to low production efficiency; at the same time, the inclination or misalignment of the spherical pad can easily cause defective products that are not assembled in place to flow into the market, and due to poor sealing, it is easy to cause dust, impurities, etc. to enter the system; Dismantling, the cost is higher. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the object of the present inven...
